FOLLOWE R-OPERATING MECHANISM FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 4:19,813, dated January 21, 1890.

Application filed March 12, 1889- Serial No. 3Q2,972. (No model.)

vide for two forward movements of the follower for every revolution of the sweep or lever, to provide for a rapid movement of the follower during the preliminary compression of each batch of material, and at the same time to provide for a more effective application of the power during the final compression of each charge or batch of the material that is being operated upon.

To the ends named the invention consists of certain novel constructions, arrangements, and combinations of elements, to be hereinafter explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional plan view of my improved follower-operating mechanism, the

view being taken on a line just below the sweep or power-lever, and the parts being represented as they appear when the follower is upon its outward or up stroke. Fig. 2 is a similar view, the parts, however, being represented as they appear when the follower is upon the half-downward or inward stroke. Fig. 3 is an enlarged sectional plan view,.parts being represented as they appear when the follower has reached its downward or inward line of travel. Fig. 4. is a detail view illustrating the parts as they appear just as the follower-operating arm is freeing itself from the pitman end. Fig. 5 is a detail view illustrating the parts as they appear after the follower has been freed from one of its operating-arms and is about to be engaged by the other. Fig. 6 is a sectional elevation of the operating mechanism, and Fig. 7 is a cross-sectional view.

In the drawings, 10 represents the baling chamber; 11, the follower, and 12 a pitman, that is connected to the follower in the ordinary manner. The end of the pitman is formed with a slot 0, and is strengthened by means of slotted plates b, which extend somewhat beyond the end of the pitman-bar to serve as supports for a block 13, formed with aconcave face 0, said block being supported by a pivot pin or bolt 15, which is carried by the plates b. The block 13 is normally held in the position in which it is shown in Fig. 5 by a spring 1', such spring, however, permitting the block at times to tilt, as illustrated in Fig. 4. At the lower end of the slot a, I arrange a rubber cushion 16.

The extending end of the pitman 12 is supported by a guiding-arm 17, which arm is provided with an upwardly-extending pin or stud 18, that passes through the slot a, the opposite end of the guiding-arm being pivot-ally connected to the frame 20, which frame is rigidly connected to a base-frame 100. The frame 20 supports a vertical shaft 21, to the upper end of which there is connected a sweep or power-lever 22, the shaft being stepped upon the lower member eof the frame 20 and guided by the upper member d of said frame. The shaft 21 carries two double arms 80 and 31, and between the said armsl mount rollers 24 and 25, the rollers being loosely mounted upon shafts 26 and 26, which extend through curved slots f, that are formed at each end of the double arms 30 and 31, anti-friction wheels or rolls 9 being also carried by the shafts 26 and 26, said anti-friction rolls or wheels resting within the slots f, the part-s being held,- as represented in the drawings, by washers '72 Just at one side of the center of the frame 100,1secure a stop 28, and upon the frame 20,

I mount two curved plates or bars 29, the

outer curved faces of said bars or plates be ing eccentric to the axis of the shaft 21, and the plates being so placed that as the shaft 21 is rotated the ends of the shafts 26 and 26 will bear upon the plates or bars, and will be moved outward from the position in which they are shown in Fig. 2 to the position in which they are shown in Fig. 1.

The operation of the improved mechanism for baling presses which has been above described is as follows: The sweep, being ad vanced in the direction of the arrow shown TOD in Fig. 3, will carry the shaft 21, and with it the double arms 30' and 31, forward in the same direction, and as the double arms so advance one of their rollers 24 or 25 will bear against the block 13, which, as before stated, is pivotally connected to the pitman 12. Then any continued forward movement of the sweep will carry the pitman downward or forward, the preliminary movement of the pitman being quite rapid, owing to the fact that its point of connection with the double arms is at a considerable distance from the axis'of the shaft 21, to which the arms are connected; but as the arms 30 and 31 move in the direction of the arrow shown in Fig. 3 the roller at the left will move towardthe axis of the shaft'21, and consequently the power applied to the sweep 'will be more advantageously utilized. A When the parts reach thepositionin which' 'they' are shown in Fig. 3, the

pitman' will strike against the stop 28, and

anyfurther lateral movement of the extending end ,of' the pitman win be checked, the

onward movement of the arms 30 and 31 cansing the block 13 to tilt to the position inwhich itis shown in Fig.4, thus providing for the easy passage of the roller carriedby the arms 30 and 31 from engagement with the block 13.

Immediately after the roller has passed from engagement with the block the elasticity of the material that is being operated upon will causethe .pitman to return tothe position in which itis shown in' Fig. 5,the pitman' 'at this time being guided by, the arm 17 and all undue shocks to the parts being overcome by the action of the elastic cushion 16. It'will be noticed that when one of the rollers leaves the block 13 itwill be at'the'inner end of the slot in its supporting-arm; but as the double arms advance the roller-shaft 260r 26 will bear upon the outer curved faces of the plates orv bars 29, and the roller will be carried to the position shown at the right in Fig. 3.

By means of the"construction above described I secure a comparatively rapid movement ofthe'followerwhen the initial compression of the material takes place, and at the same time I secure an exceedingly advantageous-application of the power when the final compression is brought about.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 7 1. The combination, with a sweep, the driving-shaft 21, double arms mounted on the latter, and the pitman having a lengthwise slot, of the pitman-guide consisting of the pivoted arm 17, having a stud which works in said slot, as shown and described. f 2. The combination, with a sweep, the driving-shaft 21, double arms having rollers at their ends and mounted on the said shaft, and the pitman having a lengthwise slot, of the pitman-guide consisting of the pivoted arm 17, whose free end connects with the pitman, and the block 13, pivoted to the end of the pitman and coworking with the double arms and their rollers, as'shown and described.
